 ### Schemas
-Schemas define the contract between producers and consumers. A schema defined in an Event Hubs schema registry helps manage the contract outside of event data, thus removing the payload overhead. A schema has a name, type (example: record, array, and so on.), compatibility mode (none, forward, backward, full), and serialization type (both Avro and Json). You can create multiple versions of a schema and retrieve and use a specific version of a schema.
